Virtual Commodore 64 Example

Vintage Simulator is a (currently 100% FREE) custom libretro front-end (sharing zero code with RetroArch) with the following features:

With VSIM you can create your own virtual collection of vintage computers, consoles, and software, all represented in 3D. Or, using the physics and memory access features, build a spacecraft with flight control software written in C64 assembler. Set up anything you can imagine by importing libretro cores, your own 3D models, and writing Lua code.
